* feat(worktrees): copy included local files before setup and agents Keep local-file materialization in one built-in lifecycle hook so workspace setup and the first agent see the completed copy. Reuse the community plugin algorithm with the source checkout supplied by the worktree hook. Co-authored-by: Carlos Precioso <github@precioso.design> * test(plugins): make worktree lifecycle checks portable on Windows Compare source checkout filesystem identity across Git and Windows path spellings. Exercise copy rollback with a destination file blocking a directory, since Git for Windows accepts directories as exclude files. --------- Co-authored-by: Carlos Precioso <github@precioso.design>
